United States Airport Code Guide

Airport codes can be confusing; sometimes the code doesn’t even share any letters with the airport it refers to! The International Air Transport Association assigns these codes to airports, and they’re an important part of air travel. However, this alphabet soup can leave the average person’s head spinning. To help you out, we’ve put together this list of airport codes in the USA. The locations are listed alphabetically by city.
